Roofing underlayment is the hidden shield between your shingles and the roof deck. Because it is out of sight, many homeowners underestimate its impact on overall roofing performance—and on the final invoice. At CountBricks, we use AI-driven voice capture to calculate every square foot, fastener, and labor minute in real time, so you always understand the true roofing underlayment cost before any felt roll is unwrapped.
• Material selection: felt, synthetic, or self-adhered membranes each carry different price points
• Roll dimensions and waste factor: wider rolls reduce seams but can create more off-cuts on smaller roof planes
• Fasteners and tapes: cap nails, plastic caps, or specialized adhesives add incremental but essential dollars
• Labor hours: steep slopes and complex valleys drive up installation time
• Local code upgrades: ice-dam protection and fire ratings may require premium products
Traditional estimates split cost at roughly 60 % labor / 40 % materials. CountBricks captures voice notes from the site walk-through, applies historic crew productivity data, and adjusts the ratio to the exact roof geometry. You see a line-item breakdown that explains why a simple gable ranch differs from a multi-pitch contemporary build—even when total square footage is identical.
Southern California material suppliers adjust pricing daily based on petroleum and logistics costs. CountBricks syncs with local supplier APIs every morning at 4 a.m., updating asphalt-saturated felt, synthetic underlayment, and peel-and-stick membrane prices automatically. Labor baselines are pegged to prevailing wage bulletins for Los Angeles County, so your roofing underlayment cost reflects real-world market dynamics rather than last quarter’s averages.
1. Speak your roof dimensions into the mobile app—no typing required
2. The AI converts voice to structured takeoff data and applies pitch multipliers
3. Live pricing feeds pull current material costs from preferred vendors
4. Historic productivity curves assign crew hours based on slope class
5. A branded PDF estimate and export-ready invoice appear in under 60 seconds
• Order material precut to length when possible to lower on-site waste
• Combine underlayment delivery with shingle loads to cut freight fees
• Schedule installation during moderate weather windows to avoid overtime

• 30-lb felt averages $0.23–$0.30 per sq ft installed in Los Angeles
• Standard synthetic runs $0.32–$0.40 per sq ft but saves roughly 15 % in labor
• Premium peel-and-stick ice shield starts at $1.00 per sq ft, typically reserved for eaves and valleys
CountBricks dynamically displays these ranges in the Estimate Builder so you can model good, better, best scenarios without reaching for a calculator.
A 1,800 sq ft roof with 6:12 pitch originally budgeted felt underlayment at $1,050. After running a real-time CountBricks comparison, the contractor switched to a mid-grade synthetic that added $180 in material but eliminated an entire half-day of labor. The final roofing underlayment cost dropped to $970, and the homeowner gained a 25-year warranty instead of 15.

The CountBricks platform shaved two full days off a 2,400 sq ft reroof by identifying that a single-ply synthetic underlayment with pre-printed nailing guides could be installed 30 % faster. The contractor reinvested the saved labor into upselling ridge ventilation, boosting overall project revenue by 12 % while keeping the client’s roofing underlayment cost below the initial budget.
